chatarena vs mcp-agent

chatarena: ChatArena is a Python library that provides multi-agent language game environments for Large Language Models. It offers a flexible framework to define players, environments, and interactions, along with user-friendly interfaces for developing and engineering LLM agents.; mcp-agent: `mcp-agent` is a simple, composable Python framework designed for building effective agents using the Model Context Protocol (MCP). It fully implements MCP, offers composable agent patterns, and supports durable execution with Temporal for robust, production-ready applications.
